A generator and process for operating a generator in which, upon a bearing failure, a braking force is applied to the rotor shaft responsive to the bearing failure. Preferably, the rotor shaft at the anti-drive end is hollow and the brake is provided in the hollow of the rotor shaft. The rotor can include a plate member extending radially inwardly from the rotor shaft inside of the hollow at the anti-drive end towards the longitudinal axis, with the brake applying the braking force to the plate member. In a preferred aspect, the brake includes a cylindrical support operably connected to the housing and extending into the hollow in the anti-drive end of the rotor shaft, a carrier plate connected to the support and extending radially from the support towards the rotor shaft, a screw thread provided on the support, and a threaded plate mounted on the screw thread, the threaded plate extending radially from the support towards the rotor shaft and being spaced from the carrier plate. Rotation of the threaded plate about the support causes the threaded plate to move towards the carrier plate, pressing the plate member of the rotor between the carrier plate and the threaded plate, thereby applying braking force thereto.
